T3 a/Z'Z whom, it" muy] concern:

Beit known that I, WM. H. BECHTEL, of Philadelphia, Pennsylvania, (assignor to myself and B. H. BAR'roL, -of the same place,) have invented certain Boring and Pumping Mechanism for Artesian Wells, and I do hereby `declarethe following Ito be `a full, clear, and exact description ot' the same, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

My invention consistsin the use,substan tially as described hereinafter, of elliptical or oval cog-wheels, in combination with the bar` or rope usedin boring Artesian wells, and with the mechanism hereinafter described, or the equivalent to the same, for seizing and releasing Jthe said bar or rope.

The object of my invention is to obtain, by the aid of the elliptical wheels, a differential reciprocating motion i'or economizing power and saving time in boring Artesia-n wells, and in raising fluid from the same.

In order to enable others skilled in the art` to make and use my invention, I will now proceed to describe the manner of carrying it in to effect.

On reference to the accompanying drawings, which form a part of this specitication, Figure l is a front view of my improved boring and pumping mechanism for Artesian wells; Fig. 2, a side view of the same, and Fig. 3 a vertical section on the line l 2, Fig. l.

Similar letters refer to similar parts throughout the several views.

A is a substantial wooden frame, to which are secured the three standards B, C, and D,

and in the lat-ter turn the two shafts E and F, which are geared together by means of the elliptical or oval wheels G and G. To the shaft F is secured a crank, H, the pin of which is connected by a rod, I, to a pin at the rear of the vertical sliding bar J, thelatter, aswell as a round rod, K, passing through and being guided by the frame A, and by a projection, u., at the upper end of the standard B. To the slidingbar "J are hung the two dogs or levers b and b', one on each side of t-he'bar K. against which the short arms of the levers are forced by springs d d, acting against the under side ofthe long arms, and secured to a projection on the said sliding bar J. The connectingrod of a small engine may be coupled directly to a crank on the shaft E; or thelatter maybe furnished with a suitable pulley for receiving a drivinglbelt. As the shaft E revolves with a uniform motion, it will communicate, through theelliptieal wheels Gr G,adifferential rotary motion to the shaft F, and these wheels are so arrangedr in respect to each other and to the crank H, which operates thesliding bar J, that the greatestleverage is exerted in elevating the said bar with a slow motion, and a lesser le-` verage in lowering the bar with a much more rapid motion.

As the sliding bar commences its upward movement the dogs or levers d and d seize the bar K, which is consequently elevated simultaneously with the sliding bar until the long Athat they will serve to sustain the bar when a cessation of its movements becomes necessary.

Economy, as regards expenditure of power and consumption of time, must result from the above-described use of the elliptical wheels, inasmuch asthe greater force is exerted inaccomplishing the most severe duty of slowly raising the heavy boring-bar and slide and the lesser force in performing the lighter duty of lowering the slide rapidly. i

In the oil regions it is the general practice to bore Artesian wells with a tool attached to a rope, which may take the place of y the bar K in the above-described machine, the dogsb and b' being so adapted to the rope as to seize and release the saine.

When this mechanism has to be used for pumping'luids from Artesian wells, the `bar K or the rope maybe removed and the pumprods connected directly to the sliding bar J; or the latter and the rod I may be disconnected from the crank and the pump-rods connected directly to the crank-pin. l

As the power required to elevate the rods'l and with the mechanism described, or the and the fluid is :much greater than that nocesequivalent to thesame, for seizing and releassary for depressing the same, the advantages i In testimony whereof l have signed my name ing purposes will' be apparent. to this specification in the presence oftwo sub I claim as my invention and desire to secure f scribing Witnesses. by Letters Patent- XVM.
